interstellar gas

基本解释

Light and radio waves are absorbed and scattered by interstellar gas and dust.
光波和无线电波能被星际气体和尘埃吸收及散射。
As the supernova blast wave slams into tenuous clouds of interstellar gas, the resulting collision heats and compresses the gas, causing it to glow.
当高速行进的超新星冲击波与稀薄的星际气体相撞时，气体受到压缩和加热，因此而发光。
A molecular cloud is a region containing cool interstellar gas and dust left over from the formation of the galaxy and mostly contains molecular hydrogen.
分子云是一个包含冷却星际气体和尘埃的区域，这些气体和尘埃是星系形成之后的残留物，主要由氢分子组成。

The visible light from it was bright enough for George Djorgovski, Mark Metzger and Shri Kulkarni of the California Institute of Technology and their colleagues to analyse, and to demonstrate that it had travelled through a cloud of interstellar gas at least 10 billion light-years from the earth.

This says that the exploding material (whatever it may be) races outwards and collides with interstellar dust and gas, producing radiation.

He chose this because the supernova that created it blew a giant bubble, known as the Vela nebula, out of the surrounding interstellar medium, and that bubble is big enough to stand in for the infinite sheet of gas.
